Abstract

The utility model discloses an easy taking type disc box whose pushing plate is provided with an annular seizing ear. The annular seizing ear, which is composed of a plurality of elastic sheets arranged as a loop, comprises a disc blocking part obliquely and prominently extending from the end face of the pushing plate to the outside of the pushing plate and a top blocking part extending from the bottom of the disk blocking part. The top blocking part is lower than the end face of the pushing plate. When the pushing plate stretches into the containing room, the top blocking part is pushed by the box body to stretch, thus the via holes of the discs are forced tightly by the obliquely expansion to the outside of the disc blocking part. When the pushing plate is pushed out of the containing room, the top blocking part elastically resets without the push of the lower end face. Under such condition, the maximum external diameter width of the disc blocking part is shorter than the aperture of the disc via hole, so the discs can be easily taken out from the pushing plate under the condition that the surface of the disc is not damaged.
